1.) an double click select an whole "word"2.) an word is something what is enclosed from an space ( " word " ) OR an "non-word"-sign ( "$word " ) before and after3.) what belongs to the group of valid word signs is defined in the syntax files in the section <Words>...</Words>But in the PHP syntax file there is no such section, because:4.) the PHP syntax file "php_spec.xml" is based on "defsource_spec.xml" and this on "def_spec.xml"5.) in this "def_spec.xml" you will find this section: <Words>0-9A-Za-z_</Words>Modify this section to include the '$' -sign as valid sign for an "word" like >>> <Words>0-9$A-Za-z_</Words>Then you can select an word like "$myVar" by an double click too.

some notes:- Modification in this basic syntax file "def_spec.xml" belongs to all syntaxes based on this base.- You can modify the "php_spec.xml" too to overwrite the settings from "def_spec.xml"... but that is an other story and can be found in the FAQ section too, ... i would have to take an look myself too.- I have no glue if this modification will have any side-effects, take care yourself and report how it works for you.

Yes, everything is right. You can also skip symbols defined in parent schema, they will be inherited. So this <Words>$</Words> will be enough.

But such change will lead to one disadvantage (at least) : Auto Completion and Code Hints for PHP variables will not work. Reason is that when you will press Ctrl+Space after $d.. something, editor will check for beginning of the word to find prefix for filtering of the completion list, and it will be $d... But to highlight all php variables, following block used: <Blocks> <Block open="$" close=""/> </Blocks>

and all variables collected without $. So nothing will be found.

The only way to solve it is to remove styles: id="variable" and name="Built-In Variables". After this variables will be not highlighted but code completion should work.

Best regards,Alex.P.S: I will think about possible solution, but have doubts that can find some easy way/correction for this. I knew this already long time ago, and this was a compromise to not place $ into word symbols. The same way it done in some other schemes. So, if not yet fixed, probably was no easy way.
